Despite the increase in the demands on collaboration between health and social welfare, the success of such schemes have been limited. The extant literatures tends to be dominated by explanations for needs or short-term outcomes of collaboration rather than systematic follow-up research to apply to the frontline. At the same time, there is no attempt to apply the theories related to collaboration in order to discuss the situation. This study explores the factors hindering such collaborative working in the frontline, through semi-structured interviews with practitioners involved in two pilot projects. A theoretical framework (Equilibrium Model-Sensemaking, E-S model) which combined Equilibrium Model of 'Interorganizational Network' of Benson(1975) and 'Sensmaking' of Weick(1995) for conceptualiing aspects of collaborations such as working atmosphere and agency was applied to the empirical study of the Public Health and Welfare Office(1995-1999) and the Social Welfare office(2004-2006) pilot projects. Data were collected over three months from 8 pilot project areas with practitioners and managers from health and social welfare. The findings show significant regional differences between pilot areas, such as the presence of active leaders and co-location, had a major impact on the ability of practitioners to effectively integrate services. In other words, active leaders tended to influence practitioners' motivation, while co-location encouraging communication between both practitioners, and thus seemed to influence the practices of collaborative working. Furthermore, through E-S model, it is interpreted that this kind of positive experiences about collaborations may impact on the current practitioners' comprehensive perspective towards health and social welfare services in general. The findings could help policy makers consider the practical ways to break down the barriers between health and social welfare.

Intravesical instillation of the bacillus Calmentte-Gu$\acute{e}$rin(BCG), an attenuated strain of Mycobacterium bovis, is an approved method for the treatment of superficial bladder cancer. Because BCG is a living organism, the potential for infection exists. BCG is generally well tolerated, with complications in less than 5% of those treated with use of current practices. The most frequent symptoms of toxicity associated with intravesical BCG immunotherapy include bladder irritation, frequency, and dysuria. Systemic reactions are less common but more serious than local side effects, and include fever, chills, malaise, rash, hepatitis, pneumonitis, arthritis and sepsis. In rare cases, BCG treatment can result in a systemic infection that requires antituberculous therapy. The pulmonary toxicity that results from intravesical BCG treatment is generally characterized by one of two types : systemic allergic reaction with pulmonary reticulonodular opacities depicted on chest radiographs with cellular findings consisting of activated lymphocytes, and actual BCG mycobacteremia with a miliary pattern depicted on chest radiographs and granuloma formation which rarely results in positive acid-fast stain or culture results. Recently we experienced two types of pulmonary complications following intravesical BCG immunotherapy in patients with superficial bladder cancer. We report two cases with a review of literatures.

An FM radio based PCL system is a passive radar technique for detecting the multiple moving targets from FM radio signals and tracking the trajectories of the targets by calculating the cross-correlation function of direct-path signal and target echo signals. However, the interference signals are received from a surveillance channel, which is designed to receive the target echo signals. Because of this problem, the target echo signals are masked by the strong interference signals and this makes it difficult to detect the true targets from the cross-correlation function. Adaptive filters are known as effective methods for suppressing the interference signals but there is a problem to present their accurate performances in the PCL system because many literatures used the cross-correlation function and the ratio of input and output power as a measure of the performance analysis. In this paper, a performance analysis method is proposed to evaluate the performance of interference cancellation algorithms. By using the property that each component of the filter weight vector is adjusted to suppress the specific interference signal, a performance measure of the interference signal suppression is defined by a function of adaptive filter weights. Based on the proposed method, we compare the performance of the adaptive filters used in the PCL system. Simulation results show that the proposed method can be very effective for evaluating the performance of interference cancellation algorithms.

Online design education, started with the establishment of cyber universities in Korea in 2001, has been operated with the development of online classes for various subjects until present and is predicted to be expanded both quantitatively and qualitatively as the concept of remote education is gradually generalized along with the growth of cyber universities and the development of digital technologies. However, regardless of such quantitative growth and possibility of development, the current online design classes are operating curriculum that is not much different from that of design department at the existing offline universities, while the concepts and roles of design and designer are changing according to the stream of digital times. Moreover, although complex elements are required to be considered since online design education is influenced by digital technological trend as being a form in which digital technology, contents, and design are all combined and advantages and features of online are required to be reflected to the maximum, the reality is different from what has been expected due to many circumstances. Online design education needs to be changed in accordance with the stream of digital times and new online design curriculum suitable for the current of future digital times and online environment are required to be developed and prepared at this moment. Accordingly, this research aims to look into the concepts and roles of design and designer changing in accordance with the stream of digital times by researching the existing literatures as well as the advantages and features of online class and to analyze the current state of curriculum of digital design and related departments at cyber universities in Korea to suggest an improvement direction of curriculum of online design class suitable for the future digital times.

We present photometric results of the δ Sct star V1162 Ori, which is extensively monitored for a total of 49 nights from mid-December 2014 to early-March 2015. The observations are made with three KMTNet (Korea Microlensing Telescope Network) 1.6 m telescopes installed in Chile, South Africa, and Australia. Multiple frequency analysis is applied to the data and resulted in clear detection of seven frequencies without an alias problem: five known frequencies and two new ones with small amplitudes of 1.2-1.7 mmag. The amplitudes of all but one frequency are significantly different from previous results, confirming the existence of long-term amplitude changes. We examine the variations in pulsation timings of V1162 Ori for about 30 years by using the times of maximum light obtained from our data and collected from the literatures. The O − C (Observed minus Calculated) timing diagram shows a combination of a downward parabolic variation with a period decreasing rate of (1/P)dP/dt = −4.22 × 10⁻⁶ year⁻¹ and a cyclic change with a period of about 2780 days. The most probable explanation for this cyclic variation is the light-travel-time effect caused by an unknown binary companion, which has a minimum mass of 0.69 M_⊙. V1162 Ori is the first δ Sct-type pulsating star of which the observed fast period decrease can be interpreted as an evolutionary effect of a pre-main sequence star, considering its membership of the Orion OB 1c association.

In this study, we investigated e kinds and names of side dishes along with their recipes and ingredients occuring in Korean cookbooks published before the 17th century. The side dishes were classified 79 kinds of Guk, 23 kinds of Jjim and Seon, 15 kinds of Gui, 3 kinds of Jeon, 7 kinds of Nureumi, 3 kinds of Bokkeum, 30 kinds of Chae, 11 kinds of Hoe, 7 kinds of Jwaban, 6 kinds of Mareunchan, 12 kinds of Pyeonyuk and 5 kinds of Jeonyak, Jokpyeon and Sundae. The earliest records were found on Guk, Jjim, Jwaban, Po and Pyeonyuk Gui, Namul and Hoe were recorded after the 1500's and Nureumi, Jeon, Jeonyak, Jokpyeon and Sundae were developed relatively late in the late 17th century. As to the kinds of side dishes, Guk was the most common. Guks cooked before the 17th century used different recipes and more types of ingredients than today, including some that are not used today. For Jjim, various seasonings were added to main ingredients such as poultry, meat, seafood and vegetable. Most of the records found for Jjim used chicken as the main ingredient. Gui was recorded as Jeok or Gui and there weren't many ingredients for Gui before the 17th century. Gui was usually seasoned with salt or soy bean sauce and broiled after applying oil. Vegetables were broiled after a applying flour-based sauce. The Jeon cooked at that time was different from the one that is cooked today in that cow organs or sparrows were soaked in oily soy bean sauce before being stewed. Nureumi, which was popular in the 17th century, but rarely made today, was a recipe consisting of adding a flour or starch-based sauce to stewed or broiled main ingredients. Chae was a side dish prepared with edible plants, tree sprouts or leaves. Chaes like Donga and Doraji were colored with Mandrami or Muroo. Hoe was a boiled Hoe and served after boiling seafood. Jwaban was cooked by applying oil to and then broiling sparrows, dudeok, and mushrooms that had been seasoned and dried. For dried Chans, beef or fish was thin-sliced, seasoned and dried or sea tangle was broiled with pine nuts juice. There are some recipes from the 17th century whose names are gone or the recipes or ingredients have changed. Thus we must to try to rebuild three recipes and develop recipes using our own foods of today.

Female phenotype of a 46,XY male may originates from male pseudohermaphroditism due to $17{\alpha}$-hydroxylase deficiency. Lack of cortisol increases adrenocorticotropic hormone (ACTH) and mineralocorticoid production, leading to low renin hypertention and hypokalemia. A 41-year-old phenotypic female presented primary amenorrhea and hypertension. In the hormonal profile, the levels of serum estradiol, testosterone, rennin, and cortisol were decreased and ACTH and deoxycorticosterone were increased. Laparoscopic bilateral gonadectomy was performed, and corticosteroid, antihypertensive drugs, and estrogen were administered. We report this case with a brief review of the literatures.

Recently, about 600 cases of marine accidents occur annually in Korea. According to many studies and analyses on occurrence of marine accidents, 70~80% of marine accidents were caused by human factors. Among the human factors, navigation officers' fatigue is very important factor. Although navigation officers' fatigue serves as an important role in marine accidents, there is no method to exactly examine the degree of officers' fatigue. Accordingly, this study analyzed human factors according to types of marine accidents and extracted important five factors affecting navigation officers' fatigue through the questionnaire survey by means of literatures and 5-point scale. In addition, evaluation factors of marine accident risks caused by fatigue factors were divided and structured by using ISM. Lastly, it found out the importance of each fatigue factor drawn by AHP and decided marine accidents that were most highly caused by navigation officers' fatigue in order. At the result, weights were high as sleep time 0.385, stress 0.302, health condition 0.139, rest time 0.099, alcohol and drug 0.074 in fatigue factors, and death and injury 0.328, collision 0.308, grounding 0.195, sinking 0.094, fire accident 0.075 in evaluation factors of marine accident risks. Therefore, the control plan to lower marine accident risks should be prepared on the basis of high weight factors.

Patients with cleft lip and palate usually show up maxillary hypoplasia. In these cases, a large amount of maxillary advancement is often needed to correct the severe deformity, but local soft-tissue scars around the maxilla restrict maxillary advancement and increase the relapse rate. Maxillary distraction osteogenesis is an effective method for facial and occlusal improvement in these patients. By gradually lengthening both the bones and the soft tissues, distracted midface can greatly increase postoperative stability and decrease the relapse rate. However, the maxillary extraoral appliances of the early days used were esthetically unappealing as well as difficult for the patient to manage. Recently, more inconspicuous intraoral distraction appliances have been developed and used with success. We acquired favorable result in two patients(bilateral 1 patient and unilateral 1 patient) with severe maxillary hypoplasia secondary to complete cleft lip and palate were treated with midface distraction using internal distractor (Zurich Pediatric Maxillary Distractor, KLS Martin, Tuttlingen, Germany). So, we report our experience with literatures.

Six cases of gangreous mastitis of goats infected spontaneously were observed clinically and pathologically in Daegu and Daejeon district. and with strain isolated purely from the infected goats, the artificial infection to the animal was examined, the sensitivity of strain to the antibiotics was tested and clinical treatment was carried out. The results obtained are summarized as follows: 1. In the six cases approximately same clinical findings were observed as the previously published literatures on gangrenous mastitis of cattle, sheep and goats. 2. The micrococcus pyogenes var aureus was highly virulent strain which was the causative organism for the gangrenous mastitis by inoculating in the udder. 3. The gangrenous mastis was probably occured by the formation of thrombosis in veins of udder. 4. In the sensitivity test, the micrococcus pyogenes var aureus resited for penicillin in 2 cases among the 6 strains, but sensitived for streptomycin, chloromycin, oxyteracycline, erythromycin, achromycin, neomycin and kanamycin in other 4 and in all case. 5. The treatment for gangrenous mastitis may be extirpated the gangrenous region surgically in the case of unilaterally or locally affected, treated by muscle injection or teat-operation in the case of severely or diffusely affected and infused antibiotics up to teat canal or treated by mammary tissue injection in the case of slightly affected.
